sql - SQL 表中的输出 : without using JOIN

Question

我有 2 个表，必须将它们连接在一起，但又不能将它们连接在一起。

表 1。

130,    'HANSEN',   'ZIP1'
130,    'HANSEN',   'ZIP2'
130,    'HANSEN',   'ZIP3'
120,    'HANSEN',   'ZIP4'
120,    'HANSEN',   'ZIP5'

表 2。

130,    'HANSEN',   'ZIP1'
130,    'HANSEN',   'ZIP2'
130,    'HANSEN',   'ZIP3'
120,    'HANSEN',   'ZIP4'
120,    'HANSEN',   'ZIP5'

想要的结果。

130,    'HANSEN',   'ZIP1'
130,    'HANSEN',   'ZIP2'        
130,    'HANSEN',   'ZIP3'
120,    'HANSEN',   'ZIP4'
120,    'HANSEN',   'ZIP5'
130,    'HANSEN',   'ZIP1'
130,    'HANSEN',   'ZIP2'
130,    'HANSEN',   'ZIP3'
120,    'HANSEN',   'ZIP4'
120,    'HANSEN',   'ZIP5'

测试脚本是否有人愿意提供帮助。

DROP TABLE TEST1;
DROP TABLE TEST2;

CREATE TABLE TEST1 ( ID  INTEGER ,key  VARCHAR(50),VALUE1 VARCHAR(50));
CREATE TABLE TEST2 ( ID  INTEGER ,key  VARCHAR(50),VALUE2 VARCHAR(50));

INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET1');
INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET2');
INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET3');
INSERT INTO TEST1 VALUES (120,  'HANSEN',   'STREET5');
INSERT INTO TEST1 VALUES (120,  'HANSEN',   'STREET6');

INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP1');
INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP2');
INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP3');
INSERT INTO TEST2 VALUES (120,  'HANSEN',   'ZIP4');
INSERT INTO TEST2 VALUES (120,  'HANSEN',   'ZIP5');

请注意，实际数据不重复

Answer 1

在两个表之间执行并集:

select * from test1
union
select * from test2

如果要在结果集中保留重复项，请使用 U NION ALL
